Nice apartment in a busy neighbourhood, very centrally located and a short walking distance from the BTS. The facilities at the apartment (pool, gym, supermarket) are great and well maintained. The apartment is noisy due to the proximity to the sky train, and there is quite some pollution due to some main roads coming together there. We stayed here for about 2 weeks.
Sudhichai seems like a nice host (I forgot sth from the fridge, which he personally handed back to me when we already left), though we had some miscommunication around the refund of the last day of our stay (we had to leave one day earlier).
All in all, if you like the liveliness of BKK and want to be close to shopping areas, this is your bet.
